Hi!
Sorry to interrupt but isn't this exactly the list of features from
EVMS? They have evmsn (ncurses interface) and emvsgui (GUI) to create,
resize, etc. volumes.

Hi.
EVMS is a much more complex tool. lvmdisk tries to emulate the fdisk
behavior and to be a good tool to do the basic setup and management
(because that "basic" i think the Logical Volume resize is a need).
